Educational Scenario: Sequence of Returns Risk

The Catastrophic Danger of Early Retirement Market Dips

Scenario A: 15% Dip in Years 1-3, Followed by Bull Run: Portfolio depletes 11 years earlier under static 4% rule
Scenario B: Bull Run First, Followed by 15% Dip Later: Portfolio survives through age 95 with substantial legacy surplus

Admin Practical Takeaway: To guard against sequence risk, maintain a 2-year cash/treasury buffer bucket outside equities to avoid liquidating depressed stock assets during early retirement bear markets.
